A major expansion programme at the Mahul refinery near Mumbai, India, has used Auma actuators in a range of valve automation applications. The refinery, which is the third largest of its kind in India, has extended facilities to include a motor lubricant manufacturing plant and a tank farm for lube oil base stock products. A key area for actuation support from Auma was provided for the tank farm which required 39 valves equipped with electric actuators for filling, emptying and mixing a range of products with different viscosity classes. Auma responded to the tender with an integral actuator solution that ensured that the new plant section could be installed and commissioned without impact on the existing plant’s operation. The actuation system provided included master stations controlling communication, the use of Modbus-RTU fieldbus protocols and explosion proof actuators.
